Fetching server results with Flex/ActionScript

I am trying to get the data provided by MyTSA (http://ift.tt/1DJzb78) for security line wait times, but I am having trouble with it. Here is the code that I have:

            import mx.events.FlexEvent;
            import mx.rpc.events.ResultEvent;

            [Bindable]
            private var url:String = "http://ift.tt/Ytfq2R";

            protected function init(event:FlexEvent):void
            {
                getWaits.send();
            }

            protected function getWaitsResult(event:ResultEvent):void
            {
                data_label.text = getWaits.lastResult.toString();               
            }

        ]]>
    </fx:Script>
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
        <s:HTTPService id="getWaits" url="{url}" result="getWaitsResult(event)"/>

Whenever I run it, I get the error code: [RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://ift.tt/YtforB" errorID=2032]. URL: http://ift.tt/YtforB"]

Any idea how I can get this to work? Am I doing something wrong?

Thanks, Jacob
